A type of rocket engine once thought impossible has just
been fired up in the lab. Engineers have built and successfully
tested what is known as a rotating detonation engine, which
generates thrust via a self-sustaining wave of detonations
that travel around a circular channel.
As this engine requires far less fuel than the combustion
engines currently used to power rockets, it could eventually
mean a more efficient and much lighter means of getting our
ships into space.
"The study presents, for the first time, experimental
evidence of a safe and functioning hydrogen and oxygen
propellant detonation in a rotating detonation rocket
engine," said aerospace engineer Kareem Ahmed of the
University of Central Florida.
